Application of Viscous Damper and Laminated Rubber Bearing Pads for Bridges in Seismic Regions

Seyed Saman Khedmatgozar Dolati et al.

Summary: This study investigates the effectiveness of a VD-LRBP system, a combination of viscous dampers and LRBPs, in reducing the displacement of the superstructure relative to the substructure caused by sliding at bearing during seismic events. The results show that applying viscous dampers can reduce relative displacement by up to 60% and effectively minimize residual displacement after an earthquake.

Shaking Table Tests of Lead Inserted Small-Sized Laminated Rubber Bearing for Nuclear Component Seismic Isolation

Gyeong-Hoi Koo et al.

Summary: This paper presents seismic shaking tests of full-scale lead-inserted small-sized laminated rubber bearings (LRB) to investigate their seismic isolation performance, dynamic characteristics, and quality consistency. The results confirm the adequate seismic isolation performance and intended dynamic characteristics of the LRB design.
